My invention relates to improvements in printing ipresses,'and it consists in the combinations, constructions, and arrangements hereinafter describedand claimed.

1 An object of my invention is to provide a printing press in which the inking cylinder carries the type and ismoved. by a Special mechanismfor printing envelopes, and the like, while the cylinder is being moved vertically. Inking rollers cooperate with the cylinder and are intermittently moved in a predetermined manner for applying inkto the type 'duringthe time the cylinder is spaced away from the matter to be printed.

" The invention further-contemplates novel means carried by the mechanism thatactuates the inking rollers for ejecting the printed matter. Y j

A further object ofmy'invention is to provide a device of the type described in which the inking cylinder is movable for bringing thetype into a position where it may be readily changed bytthe operator.

Still a further object'of the invention is to provide means for feeding envelopes one at a time to the printing device, this feedingmeans being disconnected at the will of the operator, and utilizing a suction principle as described and claimed in my co-pending application, Serial No..197,065, filed June 7th,1927. I

Other objects and advantages will appear in the following specification, and the novel features of my invention will be particularly pointed out in the appended claims.

My invention is illustratedin the accompanying drawings forminga part of this application, in which: i t

Figure 8 is asection; alongthe line 8 8 of Figure 6. v V The device. comprises a -magazine for en velop'e's, an envelope feedmechanism, a print-i mg mechanism, and an ejecting mechanism. T Will'take up-these' different features intheir urn i illagaaineforeaoelbpes v I QThe-magazine for i the envelopes is 1- shown in Flgures 1 and 3,,and'ityvill be noted that the holder 1, rectangular in cross sectionfis pivotally secured at 2 ,tothe frame 3 of the machine; The holder 1 is formed of four angle ironsthat act as guides forenvelopes i. The pivots 2 permit theholder to'be swung into the dotted line position-shown in Figure 1 when it is desired to remove the. envelopes from the bottom of theholdei' in case the envelopes becomestuck. An L- shaped plate 5 is secured to the bottomzof the holder-f1 and; supports "the lowermost envelope. The magazine mayhold cards, or

other matter, to be printed, ifdesired. It is obvious thatthe shape of the magazine may be changedfor accommodating difi'erent articles to be printed, although the present machine is designed primarily for printing 80 envelopes. v I

I Feeding mechanism j The envolpes l are placed in the; holder- 1 so that' their-flaps extend downwardly. ,My tie-pending application showshow the flaps are adapted to be sucked into a recessG as each flap is brought into a position above the recess. Figure 3, shows this recess and shows it as being disposed in a supporting platform 7. A portion of the 'lowermost envelope in the holder 1 rests upon the plate 5, while the flap of the envelope extends clear ofthe'plate. Figure 3 shows an envelope/feeding member 8 as beingin operative position, that is, in a position where it has carried. one of the envelopes 4 beneath the printing mechanism hereinafter described. The. envelope feeding member 8 when in its in operative position has its end 9 moved farenough'to theright,

when looking at Figure 3, to permit the flap of the lowermost envelope in the holder 1 to be sucked into the recess 6.

The recess communicates with a passageway 10, that in turn is in direct communication with a suction pipe 11,'by means of a compartment 12. Any means for creating a suction in the pipe 11 will suflice for the proper operation of the device. The suction will draw "downthe flap of the lowermost envelope into a position to underlie the member 8. The member, when advanced, will thereupon move between the flap and the body of the envelope until it engages with the top of the envelope, whereupon it will carry the envelopeaway from the holder 1 and into a position to underlie the printing mechanism. The means for actuating the member 8 is shown in Figures 1, 3, and5. A pulley 13, see Figure 5, is rotated in the direction'o-f the arrow by means of a cable 14 connected-to the pulley'and to a source of power, such' as amotor; The pulley is mounted upon a shaft 15 and Figure 1 shows the shaftas being provided-with a pinion 16 that meshes with a gear 17 The gear 17 is mounted upon acrank shaft 18 that carries a cam 19 of the shapeshown in Figure 5. A cam follower 20 has a roller 21 hearing against the peripheryof the cam and the follower is pivotally connected at 22 to an arm 23', see Figure 1. Movement of the cam, 19 will rock the arm about its pivot 24 in a predetermined manner. The cam times the swinging of the arm 23 'so that the :arm will move the member 8 and carry an envelope beneath theprinting mechanism at the proper time. Figure 3 shows how the arm 23is received in a slot 25 in the member 8, so that movement of the arm will move the member.

It might be well to note at this time that I provide a catch for holding the member 8 in in-operative position, even though the rest of the machine is-operating. In-case the envelopes become jammed either in the holder, or beneath the printing mechanism, I can instantly stop further movement of the member 8. I have already described how the cam moves the member-8 into in-operative position. A spring 26, see Figure 1, is connected to the frame 3, and to the cam'follower' 20, and is employed for'moving-the member into 'operativeposition. The spring is prevent-ed'frommoving the arm 23 too rapidly, due to thefact that the roller 21 bears against the cam 19, and" decreases the amount of movement'thatthe spring 26 can impart to the cam follower 20. e i i f If the operator wishes to'hold the member 8 in in-operative position, he merely swings a catch'27 mounted upon theframe 3, see Figure 1, into the dotte'd" line position where;- up'on this catch will enter an opening in the member '8 andvvill prevent the spring'26 from moving the member into" "operative posiis positioned beneath the printing mechanism. This pr nting mechanism is novel in that it also carries the inking means -and in addition carries the device that ejects the printed envelopes. The printing mechanism consists of a cylinder 28 that is hollow, as shown iii-Figure 3. This cylinder has trunnions 29 and 30 see Figure 6, that are mounted in bearings :31 and32i Thecylinder normally does not rot-ate in the bearings 31 and 32 and'is prevented from=movement by lock screws 33 that enter-depressions 34 in the trunnions '29and 30, see Figure 8: hen it is desired to change .the type carried by the cylinder, the screws 33 are loosened to permit the cylinder torbe rotated in the-bearings, butthispoint will be described later.

The cylinder carries type 35,see Figures 3 and aud t-he cylinderris cutaway at 36 for this'purpose.= Iwill firstdescribe the move ment iofthe cylinder beforesetting forth the special construction which-permits the type to be changed at will."

7 Figure -8. shows how the'bearings 31 and 32 are mounted upon rods 37 *37;and 3838, these rods being threaded forreceivingnuts 39 that secure thebearingsin proper positions-onvthe rods. 'The rods are threaded at-the upper ends for this purpose. f Figures land 2'show 'how the rods are slidably mount ed in a bearing plate 40; w' In Figure IIr ShOW how the lower ends of-the rods are secured to a cross-piece 41 that is guided in its vertical movement "-by guide stripsA-2. f The crosspi-ece llis raised andwlowered by a toggle mechanism 43, shown in Figures 1, 2, and 3. Thetoggleis connected to the cross-piece 4l' andhto theframe and'is 'moved by an arcuate-shaped arm 44, see Figure 1,that is connected to "the? toggle and to a link 45 at 46. "Figure'1 further shows how the oppo site end of the link isconnected to the crank shaft 18*s o that a rotation fof the crank shaft will reciprocate "the -:linkf This movement causes the toggle43 to movethe'cylin'der- 28 vertically from a position overlyin'g the plate 10 into printing position,-as shown in Figure 3. Y Thismovem'enttis timed. by the positioning of the crankshaft "18. and the cam 19.-'so that an envelope willtbe fed beneaththe V metrically opposite each other] The rollers 47 have trunnions 48, see Figure 6, that are slidablymounted in slots 49,- see Figure 3, in

end plates 50. Figure 3 shows the shape of each end plate 50, whileFigure 6 showshoww p The trunnions 48am kept in their respective slots 49 by spring 51, see Figures 3 and 6.

i The inking rollers 47 are given a longitudinal movement as they are carried around the cylinder 28, and'this is accomplished by cam members 52 and 53 that are carried by the rods 37 and 38, respectively. The cams 52- and 53 are positioned so as to strike the ends of the trunnions 4L8 and to force the trunnionsso that they will be moved in the direction of theirlongitudinal axis. It will be noted that the cam 52 is disposed at one end of the cylinder 28, while the cam 53 is disposed at the opposite end. This causes the rollers to first be moved in one direction and then in-the opposite, thus smoothing out the ink onthe rollers and on the cylinder 28 so that a uniform coating of ink will be applied to the type 35, as the rollers are carried thereby.

I will now describe the mechanism for carrying the rollers 47 around the cylinder 28. This movement is intermittent'and the rollers are moved through an arc of 180 degrees and then are brought to an abrupt stop to permitthe cylinder to print. In Figures 1, 2,

4,6, and .7 I show the end plates 50- as being conn'ectedto each other by rods 54; these rods,"together with the end plates, form a cage that rotates as a unit about the trunnions 29 and 30. One of the end plates has tooth-shaped depressions 55 formed therein,

see Figure 7, and these depressions receive teeth 56 of a clutch member 57. The clutch member has external teeth 58 and is in reality a gear that meshes with a pinion 59, see

Figure 6. The pinion in turn is operatively connected to a pinion 60 by means of a stub shaft 61. The pinion60 meshes with a large gear 62, see Figure 1, and this gear in turn is connected to the crank shaft 18 by means of a link 63 and an arm 64: that is attached to the shaft.

This mechanism is so interconnected that a rotation of the crank shaft 18 will oscillate the gear 62 even though the gear is moved vertically by the printing cylinder 28. An oscillation of the gear 62 will rotate the pinions 59 and 60, first in one direction and then in the opposite direction. This move ment will be carried to the gear clutch 58, see Figures 6 and 7, so that this gear will oscillate. The ratio between thev various gears is such as to cause the gear 58 to engage with the end 50 carrying the tooth-shaped depressions when the gear 58 is being rotated in one direction. The gear 58 is rotated far enough in this direction to-causetheends 50 to carry the inking rollers 47 through an arc of 180 degrees. When the gear rotates in the opposite direction the teeth 56 will ride out of the teeth 55, as shown "inFig'ure 7 and will therefore not rotate the ends 50. Figure 4 clearly shows how the gear 58 is yieldingly held in contact with the adjacent end plate 50 by a spring 65. This spring permits the gear 58 to rotate with respect to the end plate 50 when the gears rotate in one direction and to engagewith the end plate when rotated in the opposite direction.

It should be noted from Figure-3 that the slots 49 are deep enough to permit the spring 51 to force the inking rollers inwardly so that the rollers will contact with the type 35, as the rollers are carried thereby. The cylinder 28 is, of course, in its uppermost position during this movement and there is enough clearness between the cylinder and the plate 40, to permit the rollers 47 to freely pass therebetween. V Y 3 I will now described the manner of settin the type 35; In Figures 3 and 6' I show the cylinder 28 as being'pivoted with a rectangular frame 66 that is disposed inthe opening 36. This frame'is supported by a shelf 67 that extends across the cylinder and is secured to the ends of the cylinder. A plurality of blocks 68, see Figure 6, commonly used bythe printing trade, are disposed in the frame and are clamped in place by a spider 69 of standard construction; I have shown the type '35 as being positioned to print the cornercard of an envelope 4, shown by the dotted lines in Figure 6. It isobvious iou that the blocks 68 may be rearranged for 1 holding type in any positionwithin the frame 66. V p

Vhen it is desired to-chan'ge the type, the

cylinder 28 is rotated through ahalf circle,

so as to bring the type into aposition where it can beworked upon readily. "The set screws 33 are loosened'from the depressions 34.,see Figure 8, and a crank handle 70 is mounted upon'the trunnion-29 and enters a groove 7l in the trunnion, see Figure 8, sothat a-turning of the crankhandle will swing the cylinder. The nuts 39 are also loosened to permit'this ready movement. The cylinder is swunginto a position where the operatormay change the type and after this change has been made,'the cylinder is again rotated to position the typebeneath the cylinder, then the 1nuts 39 and the set screws 33 are tightenec.

Ihave shown onetype of ink fountainfor of rollers 7 3 and the lowermost rollerof this set-contactswiththe rollersd'i as they are carried around the cylinder 28. In this way ink is delivered from theroll-er .73 to the rollers 47 and the inkv is smoothed out upon the rollers 47,.because the rollers 47 ride upon the cylinder 28.

. Ejecting mechanism Reference to Fi ures 2 and 3 illustrate the manner employed Ior ejecting the printed envelopes. Certain of the rods 54 carry brushes 74 and these brushes are long enough to give a sweeping action to the top of the plate .40, as the rods are carried above the plate,and this sweeping action ejects the envelope resting upon the plate and moves it into the guide members 7 5, see Figure 1, from whichthe envelope 4 is turned into a box or other container 76.
